Raymarine RayNet (M) to STHS (M) 400mm Adapter Cable

The Raymarine RayNet (M) to STHS (M) 400mm Adapter Cable is an essential connectivity solution for integrating modern marine electronics with legacy navigation systems. This adapter is designed for vehicle and equipment modifiers who need to ensure seamless integration between older and newer hardware, preventing costly overhauls and extending the operational life of existing installations.

This cable features precision-molded connectors on both ends—a RayNet (M) plug on one side and an STHS (M) termination on the other—ensuring reliable data transmission and secure mechanical seating. At a length of 400mm (15.75 inches), this adapter provides adequate slack for routing through panel mounts, behind dashboard installations, or through cable runs without tension-induced signal degradation. The lightweight construction (0.15 lbs) minimizes installation footprint, while the shielded cable maintains signal integrity in environments prone to RF interference.

Technicians retrofitting multifunction displays, chart plotters, or autopilot systems will find this adapter invaluable for connecting legacy sensors and control modules without the need for full harness replacement. Its design is particularly beneficial for mixed-generation fleet installations, allowing for effective upgrades and retrofits in marine navigation systems.
